TECHNICAL FIELD

This invention relates generally to medical and laboratory equipment, and more specifically to one or more automated systems and methods for preparation, staining, and processing of cells and tissue preparations.

BACKGROUND

Medical and research laboratories study tissues and cells using a microscope. Researchers and medical professionals typically require a visual contrast between organelles within a cell, and between the cell and the extra-cellular matrix to study the tissues and cells. A special optical method such as a phase contrast can partially remedy this situation. A method of choice is to process specimen with a staining method such as applying dyes or colors to tissues to increase contrast. A widely used histological stain is hematoxylin and eosin (H&E). For example, cell nuclei can be stained black and/or blue in color by the hematoxylin component stains, and cell cytoplasm and most connective tissue fibers can be stained in various intensities and/or shades of red, pink, and/or orange by eosin stains. The contrasting method can reveal more than merely revealing the cell and organelles in tissue. Furthermore, with the use of antibodies and nucleic acid probes, it is also possible to detect some specific antigens and nucleic acid sequences giving information on the physiological condition of cell and tissues that can be use for medical diagnostic and research. The procedures to achieve these results are long and tedious and, as a result, expensive. Existing tissues stainers and immuno-stainers are large, expensive, and limited to few applications.

The reason for the expense is due in part to the need for tissue samples to be removed from a patient and processed by several organizations for histological examination. The characteristics of a tissue sample often provide important information regarding the health of an individual, but the characteristics are impossible to determine without assistance from multiple labs, personnel and diagnosticians due to the complexity required for staining the tissue samples.

The process typically begins by removing a tissue sample from a living organism, fixing the sample, embedding the fixed tissue in a material such as paraffin, and slicing the embedded fixed tissues into very thin sections. This procedure produces a histological specimen.

The histological specimens prepared according to either the paraffin-embedding method can be analyzed in a variety of ways, such as staining the sample to identify nucleic acids, or probing the sample with detectably-labeled antibodies.

Biological analysis using thin sections of embedded fixed tissue frequently applies to the diagnosis and prognosis of diseases and conditions such as cancer. For instance, a biopsy may be performed to determine whether a core or fragment of tissue removed from the patient is cancerous. Thus, a histological specimen is prepared from the tissue. The specimen is analyzed microscopically to determine whether the tissue exhibits the hallmarks of neoplasia or cancer.

It is known that tissue microarrays can be configured by combining hundreds of tissue samples in a single paraffin block to enable multiple tissue samples to be analyzed simultaneously. (Kononen, J, et al., Nature Medicine 4:767-768 (1998)). Thin sections from the tissue can later be analyzed using a variety of techniques, including DNA and RNA in situ hybridization and immunohistochemistry. (Bubendorf, L, et al., Cancer Res. 59:803-806 (1999)). Immunohistochemical markers or labels are often used in histology for identifying certain characteristics of a cell, for example, whether the cell is undergoing mitosis or expression of a certain antigen.

A known issue with the variety of techniques available to tissue samples is that many small labs and doctor's offices and hospitals lack the facilities to perform the analysis due to the complexity of the current techniques.

Typically, a doctor's office or laboratory can take biopsies and transfer them to laboratories for setting in paraffin or other fixative. After, tissues are set in a fixative however, transfer of the tissues to other specialized analysis locations takes place due to the complexity of preparing a slide for proper analysis. Fixed tissues can be stored within a vapor phase liquid nitrogen freezer system to maintain tissue. For example, deparafinization requires paraffin removal from the section of tissue with xylene. If the tissues are to be stained with an aqueous solution, then the slides must rehydrated in graded ethanol baths. Typically, the approach is to gently agitate the slides by repeated immersion ˜20× in each bath including xylene for 2 minutes, 100% EtOH (×2), 95% EtOH (×1), 80% EtOH (×1), and H2O (×1).

One common stain for formalin fixed paraffin tissues is Hematoxylin and Eosin (H&E). Hematoxylin stains negatively charged nucleic acids blue. The eosin stains proteins pink. The hematoxylin or the eosin can also be used by themselves in more dilute form as counterstains for immunoperoxidase staining. Such staining requires dilution of the stain 1:4 with H2O or EtOH, respectively. Slides to be stained must be washed in ethanol, and then washed with Hematoxylin, 2 minutes (×1), Running water (×1), Acid alcohol (×1), H20 (×1), Ammonia solution (×1), Running water 5 minutes (×1), 80% EtOH (×1), Eosin 15 seconds, 95% EtOH (×2), 100% EtOH (×2).

A stain appropriate for auto-staining is the “Wright Giemsa” stain which requires heat fixation by warming a slide. Next, the slide can be exposed to alcohol, 30% to 80. The stain remains on the slide for 30 to 60 seconds, followed by a running water rinse, drying and covering with oil or slide adhesive.

Another stain used for slides includes a benzidine stain, that is a specialized stain configured to identify erythroid cells. To stain such a slide requires a methanol bath, 10-15 seconds followed by benzidine for 5 minutes, then peroxide, dionized water for 2.5 minutes, hematoxylin stain for 1.5 minutes, and a water rinse.

The above sampling of staining protocols and chemicals provides ample reason why such complex procedures are performed in specialized laboratories. Given the different protocols for preparing slides for stains, the toxic chemicals used such as benzidine, typical doctor's offices and local laboratories have limited resources for known auto-staining systems that are capable of a plurality of auto-stainings. Typically, such local operations will invest in simple stain auto-stain systems.

Accordingly there is a need for an efficient and reduced complexity system and method for tissue staining and analysis that enables laboratory analysis and staining of tissue samples.

DETAILED DESCRIPTION

Those with skill in the computing arts will recognize that the disclosed embodiments have relevance to a wide variety of applications and architectures in addition to those described below. In addition, the functionality of the subject matter of the present application can be implemented with the assistance of software, hardware, or a combination of software and hardware. The software portion can be stored in a memory or recording medium and executed by a suitable instruction execution system such as a microprocessor.

Embodiments herein relate to apparatuses, methods and/or systems for auto-staining of slides for medical purposes. Certain embodiments disclosed herein can be performed with the use of a computer and software. By way of example, and with reference to FIG. 1, an exemplary computing system for implementing the embodiments includes a general purpose computing device in the form of a computer 10. Components of the computer 10 can include, but are not limited to, a processing unit 20, a system memory 30, and a system bus 21 that couples various system components including the system memory to the processing unit 20. The system bus 21 can be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnect (PCI) bus also known as Mezzanine bus.

The computer 10 typically includes a variety of computer readable media. Computer readable media can be any available media that can be accessed by the computer 10 and includes both volatile and nonvolatile media, and removable and non-removable media. By way of example, and not limitation, computer readable media can comprise computer storage media and communication media. Computer storage media includes volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Computer storage media includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital video disks (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by the computer 10. Communication media typically embodies computer readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. Combinations of the any of the above should also be included within the scope of computer readable media.

The system memory 30 can include computer storage media in the form of volatile and/or nonvolatile memory such as read only memory (ROM) 31 and random access memory (RAM) 32. A basic input/output system 33 (BIOS), including the basic routines that help to transfer information between elements within computer 10, such as during start-up, is typically stored in ROM 31. RAM 32 typically contains data and/or program modules that are immediately accessible to and/or presently being operated on by processing unit 20. By way of example, and not limitation, FIG. 1 illustrates operating system 34, application programs 35, other program modules 36 and program data 37. FIG. 1 is shown with program modules 36 including an image processing module in accordance with an embodiment as described herein.

The computer 10 can also include other removable/non-removable, volatile/nonvolatile computer storage media. By way of example only, FIG. 1 illustrates a hard disk drive 41 that reads from or writes to non-removable, nonvolatile magnetic media, a magnetic disk drive 51 that reads from or writes to a removable, nonvolatile magnetic disk 52, and an optical disk drive 55 that reads from or writes to a removable, nonvolatile optical disk 56 such as a CD ROM, DVD ROM, and/or other optical media. Other removable/non-removable, volatile/nonvolatile computer storage media that can be used in the exemplary operating environment include, but are not limited to, magnetic tape cassettes, flash memory cards, digital versatile disks, digital video tape, solid state RAM, solid state ROM, and the like. The hard disk drive 41 is typically connected to the system bus 21 through a non-removable memory interface such as interface 40, and magnetic disk drive 51 and optical disk drive 55 are typically connected to the system bus 21 by a removable memory interface, such as interface 50. An interface for purposes of this disclosure can mean a location on a device for inserting a drive such as hard disk drive 41 in a secured fashion, or a in a more unsecured fashion, such as interface 50. In either case, an interface includes a location for electronically attaching additional parts to the computer 10.

The drives and their associated computer storage media, discussed above and illustrated in FIG. 1, provide storage of computer readable instructions, data structures, program modules and other data for the computer 10. In FIG. 1, for example, hard disk drive 41 is illustrated as storing operating system 44, application programs 45, other program modules, including specimen processing module 46 and program data 47. Program modules 46 is shown including an specimen processing module, which can be configured as either located in modules 36 or 46, or both locations, as one with skill in the art will appreciate. More specifically, specimen processing modules 36 and 46 could be in non-volatile memory in some embodiments wherein one or more specimen processing modules run automatically in an environment. In other embodiments, specimen processing modules could be part of an embedded system. Note that these components can either be the same as or different from operating system 34, application programs 35, other program modules, including specimen processing module 36, and program data 37. Operating system 44, application programs 45, other program modules, including specimen processing module 46, and program data 47 are given different numbers hereto illustrate that, at a minimum, they are different copies. In one embodiment, a user can enter commands and information into the computer 10 through input devices such as a tablet, or electronic digitizer, 64, a microphone 63, a keyboard 62 and pointing device 61, commonly referred to as a mouse, trackball or touch pad. Other input devices (not shown) can include a satellite dish, scanner, or the like. These and other input devices can be connected to the processing unit 20 through a user input interface 60 that is coupled to the system bus, but can be connected by other interface and bus structures, such as a parallel port or a universal serial bus (USB). A monitor 91 or other type of display device can be connected to the system bus 21 via an interface, such as a video interface 90. The monitor 91 can also be integrated with a touch-screen panel or the like. Note that the monitor and/or touch screen panel can be physically coupled to a housing in which the computing device 10 is incorporated, such as in a tablet-type personal computer. In addition, computers such as the computing device 10 can also include other peripheral output devices such as speakers 97 and printer 96, which can be connected through an output peripheral interface 95 or the like.

The computer 10 can operate in a networked environment using logical connections to one or more remote computers, which could be other cell phones with a processor or other computers, such as a remote computer 80. The remote computer 80 can be a personal computer, a server, a router, a network PC, PDA, cell phone, a peer device or other common network node, and typically includes many or all of the elements described above relative to the computer 10, although only a memory storage device 81 has been illustrated in FIG. 1. The logical connections depicted in FIG. 1 include a local area network (LAN) 71 and a wide area network (WAN) 73, but can also include other networks. Such networking environments are commonplace in offices, enterprise-wide computer networks, intranets and the Internet. For example, in the subject matter of the present application, the computer system 10 can comprise the source machine from which data is being migrated, and the remote computer 80 can comprise the destination machine. Note however that source and destination machines need not be connected by a network or any other means, but instead, data can be migrated via any media capable of being written by the source platform and read by the destination platform or platforms.

When used in a LAN or WLAN networking environment, the computer 10 is connected to the LAN through a network interface or adapter 70. When used in a WAN networking environment, the computer 10 typically includes a modem 72 or other means for establishing communications over the WAN 73, such as the Internet. The modem 72, which can be internal or external, can be connected to the system bus 21 via the user input interface 60 or other appropriate mechanism. In a networked environment, program modules depicted relative to the computer 10, or portions thereof, can be stored in the remote memory storage device. By way of example, and not limitation, FIG. 1 illustrates remote application programs 85 as residing on memory device 81. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers can be used.

Referring now to FIG. 2, a system for enabling efficient and local auto-staining functionality is depicted in accordance with various embodiments. “Auto-staining” as used herein refers to methods and/or systems that enable automated staining of tissues on slides. More particularly, “auto-staining” herein includes staining to enable biological analysis of thin sections of embedded fixed tissue or other matter, for example for diagnosis and prognosis of diseases and conditions such as cancer. Thus, a histological specimen can be analyzed microscopically after “auto-staining”.

Tissue microarrays can be configured by combining hundreds of tissue samples in a single paraffin block to enable multiple tissue samples to be analyzed simultaneously. Embodiments herein also enable “auto-staining” for a nucleic acid (DNA/RNA) microarray. A nucleic acid microarray is a support, which can be a slide. Laboratories detect sequences by hybridization using nucleic acid microarrays. Typically, a slide will contain dots of synthesized or tissue extracted nucleic acid.

Embodiments herein further enable “auto-staining” of protein/peptide microarrays in which peptides are extracted from tissues and are then are fixed on a slide for subsequent detection by antibodies.

More specifically, the auto-stainer system in accordance with embodiments herein includes methods and systems for labeling and staining tissue specimens that are attached to slides. Additionally, the labeling and staining methods and systems apply to other types of labeling and samples. For example, other types of sample staining include but are not limited to, fluorescent applications such as FISH (fluorescent in situ hybridization), nucleic acid microarray hybridization, and protein microarray labeling.

In a nucleic acid microarray hybridization protocol, a nucleic acid (DNA, RNA or chemically analogous molecules) are extracted from biological material or synthesized. The nucleic acid extract is fixed onto a support such as a glass slide and the resulting support is processed for hybridization using various labeled nucleic acid or analog probes.

The nucleic acid probes can then be detected using various fluorochromes. (Using an enzymatic colorimetric method instead or even a radioactive tracers would be a conceptually trivial implementation.)

In a protein microarray protocol, dots of proteins extracted from tissues are fixed into a slide and processed by methods very similar to immunohistochemistry (“IHC”) for the detection of protein antigen.

As shown, the system can include one or more auto-staining instruments 100A and/or 100B. Each of auto-staining instruments 100A and/or 100B can include one or more auto-staining modules 105A and/or 105B, and each auto-staining module 105A/105B is configured to receive one of self-contained sample processing receptacles 110A-110F. Each of the one or more self-contained sample processing receptacles 110A-110F is configured to receive a tissue sample in need of staining, processing or the like, such as a tissue on one of slides 120A-120C.

Each of self-contained sample processing receptacles 110A-110F are configured as sealable chambers to enable processing therein independent from other self-contained sample processing receptacles in a same auto-staining instrument 100A/100B. For example, a single auto-staining instrument 100A can apply different staining protocols to each different self-contained sample processing receptacle 110A-110F as are present in the auto-staining instrument 110A, limited only by the availability of reagents either on board or disposed within each self-contained sample processing receptacle 110A/110B. Each self-contained sample processing receptacle 110A/110B can apply reagents present in-situ and/or reagents supplied by the auto-staining instrument as required by a given staining protocol. According to an embodiment, the staining protocol can be determined by operator 150 when determining which self-contained sample processing receptacle 110A/110B is appropriate for a staining protocol.

FIG. 2 further illustrates an operator 150. As described, according to an embodiment, operator 150 can determine which staining protocol to apply to any given tissue by choosing an appropriate self-contained sample processing receptacle 110A-110F. For example, one or more self-contained sample processing receptacles can be configured as including one or more reagents, such as beads or the like, within the self-contained sample processing receptacles 110A/110B. The beads can be predetermined to be appropriate for one or more specific type of staining protocol. Alternatively or in addition to in-situ reagent beads, reagents can be supplied via a fluidic system incorporated into auto-staining instrument 100A in one or more of containers 130A-130F. Additionally, the self-contained sample processing receptacles 110A/110B can be configured as requiring additional reagent via auto-staining instrument 100A/100B. Also, in one embodiment, self-contained sample processing receptacle 110A/110B could include a partial-reagent bead requiring additional chemicals via receptacles 130A-130F, or the like. In each case, however, the processing takes place within a sealed chamber of the self-contained sample processing receptacle 110A/110B.

As shown in FIG. 2, operator 150 can place slide 120A into self-contained sample processing receptacle 110B and can place self-contained sample processing receptacle 110B into auto-staining module 105B of auto-staining instrument 100A. In some embodiments, self-contained sample processing receptacle 110B can be placed into auto-staining module 105B while auto-staining is being performed in auto-staining module 105A on a different self-contained sample processing receptacle 110A within same auto-staining instrument 110A. Moreover, a first auto-staining can be performed in auto-staining module 105A while a different second auto-staining can be performed in any different auto-staining module, such as auto-staining module 105B. For example, a portion of a first auto-staining procedure can be performed using auto-staining module 110A while a portion of a second auto-staining procedure is performed using auto-staining module 110B. For instance, the portion of the first auto-staining procedure and the portion of the second auto-staining procedure can be performed in a concurrent fashion. In some embodiments, the first auto-staining procedure and the second auto-staining procedure can be the same or different. More particularly, as one of skill in the art will appreciate, staining of tissue samples can be a long process requiring heating, cooling, applying stain, rinsing of reagent and the like. Depending on the protocol required for a particular staining event, the length of time required (according to some measure of some metric) within each self-contained sample processing receptacle can be different. Thus, according to an embodiment, rather than requiring a largest common denominator of time to determine how many staining protocols can be performed, each self-contained sample processing receptacle is configured to be independent from other self-contained sample processing receptacles even within the same auto-staining instrument 100A/100B.

In various embodiments, one or more reservoirs 130A-130F can be coupled to one or more auto-staining instruments 100A and/or 100B. For example, reservoirs 130A-130F can be used as vessels or reservoirs for reagents, buffers, liquids, semi-liquids, gases, wastes and/or other fluids. In various embodiments, a reagent can include antibodies, molecular probes, alcohols, dyes, and/or enzymes, among others.

In one example, auto-staining instruments 100A and 100B can share contents of each of reservoirs 130A-130F via a sharing system. In one instance, auto-staining instrument 100A and auto-staining instrument 100B can be separately coupled to one or more of reservoirs 130A-130F. In another instance, auto-staining instrument 100B can be coupled to one or more of reservoirs 130A-130F through auto-staining instrument 100A. In various embodiments, auto-staining instruments 100A/100B can be “daisy chained” together to access one or more of reservoirs 130A-130F. For example, a first auto-staining instrument can be coupled to one or more of reservoirs 130A-130F, a second auto-staining instrument can be coupled to the first auto-staining instrument, and a third auto-staining instrument can be coupled to the second auto-staining instrument. The second auto-staining instrument can access one or more of reservoirs 130A-130F through the first auto-staining instrument, and the third auto-staining instrument can access one or more of reservoirs 130A-130F through the second auto-staining instrument.

Turning now to FIG. 3, Auto-staining instruments 100A and 100B are depicted, according to various embodiments. As shown, auto-staining instrument 100A can include auto-staining modules 105A-105J, and auto-staining instrument 100B can include auto-staining modules 105K-105T.

Referring now to FIGS. 4 and 5, auto-staining instrument 100A is depicted, according to various embodiments. As shown in FIG. 4, operator 150 can place self-contained sample processing receptacle 110A into auto-staining module 105B. As illustrated, auto-staining module 105B has its door in an open position. FIG. 5 shows self-contained sample processing receptacle 110A in auto-staining module 105B.

Referring now to FIG. 6, a portion of an auto-staining instrument is depicted according to various embodiments. As illustrated, in some embodiments, auto-staining instrument 100A can include one or more fluidic ports or connectors 160A-160C that can be used in connecting auto-staining instrument 100A to various reservoirs, such as reservoirs 130A-130F. For example, fluidic connector 160A can be coupled to a selection valve that can select among reservoirs 130A-130D. Reservoirs 130A-130D can also be used for reagents, buffers, liquids, and/or other fluids. Fluidic connector 160B can be coupled to reservoir 130E that can be used for water, and fluidic connector 160C can be coupled to reservoir 130F that can be used for waste.

In one or more embodiments, reservoirs could be used to store some fluids. For example, a fluidic connector can be coupled to a water supply. For instance, a laboratory can have a distilled or de-ionized water supply that can be coupled to fluidic connector 160B. In another instance, the laboratory can have a waste system that can be coupled to fluidic connector 160C.

As illustrated, auto-staining instrument 100A can include one or more data ports 170A-170C. In various embodiments, one or more data ports can transmit and/or receive data with various systems, subsystems, networks, and/or devices, and data can be transferred through, to, and from various mediums. For example, auto-staining instrument 100A can use data port 170A in communicating data via Ethernet, universal serial bus (USB), RS-232 signaling, RS-485 signaling, IEEE 1394 (e.g., FireWire), optical fiber, DSL, a public switched telephone network (PSTN), ISDN, general purpose IO (GPIO), IEEE 1284, IEEE 488 (e.g., GPIB), MIDI signaling, 1 ²C (Inter-Integrated Circuit), SCSI, SPI (serial peripheral interface), TWI (two-wire interface), MICROWIRE, and/or 1-Wire, among others.

In some embodiments, an auto-staining instrument can communicate data in a wireless fashion. For example, auto-staining instrument 100A can use data port 170A to communicate data in a wireless fashion.

More specifically, after a user 150 inserts a sample into a self-contained sample processing receptacle, and the sample and self-contained sample processing receptacle are inserted into auto-staining instrument, the auto-staining system can address a database holding data concerning each procedure with a list of appropriate samples. For example, FIG. 7 illustrates memory mediums 177A-177C, and FIG. 9 illustrates database 240.

Depicted within block 1550 is optional block 15502, which provides for receiving the first identification data via one or more of a computer-readable color, hologram, bar code (e.g., a one or more dimensional bar code) and/or a radio frequency identification (RFID) tag, such as ID 365.

Referring now to FIG. 16, another flow diagram illustrates a method in accordance with an embodiment. Block 1610 provides for receiving first identification information. In one example, auto-staining instrument 100A can receive the first identification information via auto-staining module 105B. In another example, one or more of PCD 230A, DTCD 230B, SCD 230C, and/or database 240 can receive the first identification information. In various embodiments, identification information (e.g., first identification information, second identification information, third identification information, etc.) can be received from one or more of a computer-readable color, hologram, bar code and/or a radio frequency identification (RFID) tag, among others, included on and/or within a first self-contained sample processing receptacle (e.g., self-contained sample processing receptacle 110A). Next, block 1620 provides for determining a first sample auto-staining based on the first identification information. In various embodiments, one or more sample auto-staining procedures can be determined based on the first identification information. For example, Table 1, below, shows various possible identifications associated with various possible auto-staining procedures.

Next, at 1630, a first sample staining procedure may be determined based on the first identification information. In various embodiments, one or more sample staining procedures may be determined based on the first identification information. For example, Table 1 shows various possible identifications associated with various possible staining procedures.

TABLE 1 Identification A Staining Procedure B, Staining Procedure D Identification B Staining Procedure A Identification C Staining Procedure D, Staining Procedure B Identification D Staining Procedure C, Staining Procedure A, Staining Procedure E Identification E Staining Procedure B Identification F Staining Procedure A

In various embodiments, information associated with Table 1 may be stored in a data structure that may be stored in a memory medium that may be accessed by one or more of instrument units 100A-100C, PCD 230A, DTCD 230B, SCD 230C, and/or database 240 to determine a staining procedure (e.g., the first staining procedure, etc.). For example, referring to FIG. 7, the data structure may be stored in one or more of memory mediums 177A-177C. In another example, the data structure may be stored in a memory medium included in one or more of PCD 230A, DTCD 230B, SCD 230C, and/or database 240 as shown in FIG. 9. In some embodiments, the portions of the data structure may be distributed among two or more of memory mediums 177A-177C and memory mediums of DTCD 230B, SCD 230C, and/or database 240. In some embodiments, the data structure may be indexed based on information associated with the first identification information.

Next, at block 1630, the first staining procedure can be performed.

Turning now to FIG. 17, a flow diagram is depicted, according to various embodiments. At 1710, second identification information may be received. For example, the second identification information may be received from a second self-contained sample processing receptacle (e.g., 110B). In various embodiments, the second identification information may be different from the first identification information or the second identification information may be the same as the first identification information. In one example, instrument unit 100A (FIG. 2) may receive the second identification information via staining module 105C. In a second example, instrument unit 100B may receive the second identification information via staining module 105K. In another example, one or more of PCD 230A, DTCD 230B, SCD 230C, and/or database 240 (FIG. 9) may receive the second identification information.

Next, at 1720, a second sample staining procedure may be determined based on the second identification information. In various embodiments, two or more sample staining procedures may be determined based on the second identification information. In some embodiments, various methods, data structures, memory mediums, and/or systems associated with block 1620 may be used to realize and/or implement block 1720 by using the second identification information in place of the first identification information.

In some embodiments, blocks 1620 and 1720 may determine the same staining procedure even when the first identification information and the second identification information differ. For example, referring to Table 1, the first identification information may be associated with “Identification F” and the second identification information may be associated with “Identification B”, and each of “Identification F” and “Identification B” is associated with “Staining Procedure A”. This may allow various systems and/or methods described herein to be configurable. For instance, “Identification F” may have been previously associated with “Staining Procedure C”, and various systems and/or methods described herein have been configured to associate “Identification F” with “Staining Procedure A”. This may be more desirable than configuring or re-configuring identifications on various self-contained sample processing receptacles. For example, one or more of the identifications of respective self-contained sample processing receptacles 110A-110F may be read-only, and it may not be possible to change their identification information. In another example, one or more of the identifications of respective self-contained sample processing receptacles 110A-110F may include read-write capabilities, and it may be time-consuming to re-configure a number of self-contained sample processing receptacles.

Next, at 1730, the second staining procedure may be performed.

In various embodiments, staining instruments 100A-100C, PCD 230A, DTCD 230B, SCD 230C, and/or database 240 may execute instructions that implement various methods and/or portions of various methods described herein in a concurrent fashion. In one example, time slicing may be used to provide an apparent simultaneous performance of two or more tasks by a computer system. In another example, two or more tasks may be performed in parallel by one or more computer systems. In some embodiments, concurrent processing may include executing two or more tasks in parallel and/or in an apparent simultaneous performance of two or more tasks by computer system. For example, a scheduler may be implemented that may allow multi-tasking and/or time slicing to occur. For instance, the scheduler may allow execution of processes in a round robin and/or priority fashion, among others. In some embodiments, two or more virtual machines may be implemented that may allow multi-tasking to occur.

In various embodiments, a computer system may include various components that may implement concurrency. For example, one or more of instrument units 100A-100C, PCD 230A, DTCD 230B, SCD 230C, and/or database 240 may include a direct memory access (DMA) controller. For instance, a DMA controller of instrument unit 100B may be used to transfer data between instrument units 100A and 100C with minimal or no instruction execution by processor 175B of instrument unit 100B.

Referring now to FIG. 18, a flow diagram of a staining procedure is depicted, according to various embodiments. In various embodiments, user input may be used in determining one or more staining procedures to be performed. At 1810, various options can be communicated to a user (e.g., operator 150). In various embodiments, a user interface may be used to communicate information to a user and/receive information from the user. In some embodiments, the user interface may include a display unit that may be used to display options to the user. For example, the display unit can include one or more of a screen, a liquid crystal display (LCD), an organic light emitting diode (OLED) display, and/or any device operable to convey information to the user. For instance, one or more of PCD 230A, DTCD 230B, and/or SCD 230C may display the options to the user.

Next, at 1050, user input information may be received, where the user input information is associated with one or more sample staining procedures. In various embodiments, one or more of staining modules 105A-105T, instrument units 100A-100C, PCD 230A, DTCD 230B, and/or SCD 230C may receive the user input information via a user interface. For example, the user interface may include one or more of buttons, keys of a keyboard, a mouse, a graphical user interface (GUI), a voice interface, a gesture interface, a smart-card interface, a touch screen, a joy stick, and/or anything that would allow a human to interface with a computer system.

For example, the user may select one or more staining procedures associated with an identification shown in Table 1. In some embodiments, the user may select one or more staining procedures which may not be available in Table 1. In one example, the user may select “Staining Procedure E”, “Staining Procedure A”, “Staining Procedure C” which is a reverse order of staining procedures associated with identification information “Identification D”. In another example, the user may select “Staining Procedure D” and “Staining Procedure C”. In various embodiments, the user input may override identification information received from a computer-readable color, hologram, bar code and/or a radio frequency identification (RFID) tag, among others, included on and/or within a cartridge (e.g., self-contained sample processing receptacle 110A).

Next, at 1060, a first sample staining procedure may be determined based on the user input information, and, at 1840, the first sample staining procedure may be performed.

Referring now to FIG. 19, a flow diagram depicts a staining procedure, according to various embodiments. At 1900, one or more amounts of respective one or more reservoirs 130A-130I may be determined. For instance, various capacities of reservoirs may be required for the staining procedure. For example, the staining procedure may need a first amount from reservoir 130A and a second amount from reservoir 130C. The first and second amounts may be the same or different. The staining procedure may need a capacity available in a reservoir, e.g., in one or more of waste reservoirs 130G-130I. In some embodiments, instrument unit 100A may not be coupled a waste reservoir configured to receive a type of waste generated by the staining procedure, even though various required reagents are available. Thus, it may not have a capacity for that type of waste.

If capacity is not available, an alert may be sent at 1905. For example, instrument unit 100A may indicate visual and/or audio information about the determination from 1900. In another example, a message, that may include information associated with the determination at 1900, may be transmitted to a computer system, pager, mobile telephone, etc.

If capacity is available, the staining procedure may proceed to 1910, where a first fluid may be selected through fluidic selection device 210. For example, fluidic selection device 210 may receive selection information, and fluidic selection device 210 may select a fluid based on the selection information. Next, at 1920, the first fluid (e.g., from reservoir 130C) can be controlled into a chamber 300 via fluidic valve 310A and channel 330A. Next, at 1930, a temperature of a slide in the chamber may be controlled. In various embodiments, the temperature control may lower or raise temperature. Moreover, the temperature control may adjust temperature to and maintained at a level for a period of time. In some embodiments, the temperature control may include adjusting temperature to one level for a period of time and then adjusting temperature to another level for another period of time. For example, the slide may be heated and/or cooled.

Next, a second fluid may be selected at 1940. Similar to what is described above, fluidic selection device 210 may select and deliver fluid from reservoir 130A to staining instrument 100A. At 1950, the first fluid may be evacuated from chamber 300, and at 1960, the second fluid may be pumped into chamber 300 via fluidic valve 310B and channel 330B. In some embodiments, the first fluid may be evacuated from chamber 300 while the second fluid is being pumped into chamber 300. In various embodiments, evacuating a fluid from chamber 300 may occur through gravity, a vacuum pumping action, and/or by the introduction of pressure from an incoming fluid.

Next, at 1970, a temperature of a slide in the chamber may be controlled. At 1980, the second fluid may be evacuated from chamber 300, and at 1990 water may be pumped into chamber 300. In some embodiments, the second fluid may be evacuated from chamber 300 while the water is being pumped into chamber 300. In some embodiments, flushing the chamber may include pumping in water, air, a neutralizing agent, and/or a sterilizing agent. Next, at 1992, the water may be evacuated from chamber 300, and, at 1994 the second fluid may be pumped into chamber 300 via fluidic valve 310A and channel 330C which may include a reagent bead 340C. In various embodiments, the second fluid flowing through channel 330C may cause one or more portions of reagent bead 340C to dissolve. In some embodiments, the water may be evacuated from chamber 300 while the second fluid is being pumped into chamber 300.

Next, at 1996, contents of chamber 300 may be agitated and/or mixed. As described above, the cartridge may include an elastomer element and a magnetic material. In some embodiments, the magnetic material may include a magnet. In various embodiments, a staining module may apply a magnetic field that varies at one or more frequencies. The magnetic field may cause forces to be applied to the magnetic material and, thus, to the elastomer element which causes the contents of the chamber to be agitated and/or mixed. In some embodiments, agitating and/or mixing the contents of chamber 300 may cause one or more portions of reagent bead 340C to dissolve and/or mixed with the contents of chamber 300.

At 1998, the chamber may be evacuated. In various embodiments, air may be allowed to enter the chamber so a vacuum may not be created. In some embodiments, one or more portions of the contents of chamber 300 may be evacuated through fluidic valve 310D.

It is noted that in various embodiments of one or more of the method elements may be performed concurrently, performed rapidly enough to be viewed as concurrent to a user, in a different order, or be omitted. Additional elements may be performed as desired.

While the subject matter of the application has been shown and described with reference to particular embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and detail can be made therein without departing from the spirit and scope of the subject matter of the application, including but not limited to additional, less or modified elements and/or additional, less or modified steps performed in the same or a different order.

Those having skill in the art will recognize that the state of the art has progressed to the point where there is little distinction left between hardware and software implementations of aspects of systems; the use of hardware or software is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer can opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer can opt for a mainly software implementation; or, yet again alternatively, the implementer can opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein can be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which can vary. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and or firmware.

The foregoing detailed description has set forth various embodiments of the devices and/or processes via the use of block diagrams, flowcharts, and/or examples. Insofar as such block diagrams, flowcharts, and/or examples contain one or more functions and/or operations, it will be understood by those within the art that each function and/or operation within such block diagrams, flowcharts, or examples can be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or virtually any combination thereof. In one embodiment, several portions of the subject matter described herein can be implemented via Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs), digital signal processors (DSPs), or other integrated formats. However, those skilled in the art will recognize that some aspects of the embodiments disclosed herein, in whole or in part, can be equivalently implemented in standard integrated circuits, as one or more computer programs running on one or more computers (e.g., as one or more programs running on one or more computer systems), as one or more programs running on one or more processors (e.g., as one or more programs running on one or more microprocessors), as firmware, or as virtually any combination thereof, and that designing the circuitry and/or writing the code for the software and or firmware would be well within the skill of one of skill in the art in light of this disclosure. In addition, those skilled in the art will appreciate that the mechanisms of the subject matter described herein are capable of being distributed as a program product in a variety of forms, and that an illustrative embodiment of the subject matter described herein applies equally regardless of the particular type of signal bearing media used to actually carry out the distribution. Examples of a signal bearing media include, but are not limited to, the following: recordable type media such as floppy disks, hard disk drives, CD ROMs, digital tape, and computer memory; and transmission type media such as digital and/or analog communication links using TDM (time division multiplexing) or IP (Internet protocol) based communication links (e.g., packet links).

The herein described aspects depict different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled”, to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable”, to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components.

While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications can be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of this subject matter described herein. Furthermore, it is to be understood that the invention is defined by the appended claims. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims can contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.).
